Introduction: During this chemistry laboratory, students were given different solids and solutions to experiment with, such as: aluminum, copper, glass, plastic, and wood, NaCl, distilled water, tap water, ethanol, HCl, NH 3 , Gatorade, fruit punch and soda. The purpose of the experiment was to determine the electrical conductivity of the variety of the given solids and solutions and to deduce what this means about the atomic-level structure of these materials. Experimental Procedure: Materials used: Aluminum, Copper, Glass, Plastic, Wood 0.1 M NaCl, 0.001 M NaCl, Distilled Water, 0.1 M Ethanol, 0.1 M HCl, 0.1 M NH 3 , Gatorade, Fruit punch, Soda Large crystal of NaCl Conductivity indicator Multi-well plastic Chemplate Procedures: 1. Using the conductivity indicator, measure the conductivity of the given solids, which are aluminum, copper, glass, plastic and wood. Determine if these given solids are conductive or non-conductive. 2. Use the Multi-well plastic chemplate and fill the depressions with: 0.1 M NaCl, 0.001 M NaCl, Distilled Water, 0.1 M Ethanol, 0.1 M HCl, 0.1 M NH 3 , Gatorade, Fruit punch, Soda. 3. Now use the conductivity indicator to measure each of the previous solutions to determine if it is a strong, weak, or non-electrolyte. 4.
